UX team suggests to replace the pie chart with bar chart.
This has three parts:
1) The bar chart - the easy part, just going to take some jQuery bar chart
2) Change of the data shown - rather than packages, it's going to show the technologies. Based on tags.
3) It's not going to show every tag, as that would be a bit messy. Rather it will show the "high level technologies".
For that, I'm implementing a tree hierarchy of tags.
